Which statement best describes the relationship between cell cycle regulation and apoptosis in tissue homeostasis?
Show answer and explanation
Correct answer: Checkpoint and apoptosis pathways are coupled, so severe damage triggers death over division
Cell cycle regulation and apoptosis are linked: if damage is detected at checkpoints and cannot be repaired, apoptotic pathways are activated to eliminate the cell, balancing proliferation and death to maintain tissue homeostasis.
